Interfacing Ultrasonic Sensor with Arduino Uno

In this tutorial we will learn about integrating HC-SR04 ultrasonic distance sensor with Arduino Uno. Ultrasonic sensors are commonly used for obstacle detection and distance measuring applications. The sensor works on the same principles of a radar system, which converts electrical energy into acoustic waves and vice versa. The HC-SR04 ultrasonic sensor is based on the principle of SONAR, which is an abbreviation of Sound Navigation Ranging. This sensor is used in many hobby projects where there is a need...

Interfacing HC-SR04 Ultrasonic Distance Sensor with ATmega32 Microcontroller

Introduction

This project uses an ultrasonic sensor to indicate the distance of any object from it. Here we have made a setup based on a microcontroller in which real time distance is sensed by an ultrasonic sensor and displays measured distance on an LCD display.

Interfacing HC-SR04 Ultrasonic Sensor with Raspberry Pi

HC-SR04 Ultrasonic Sensor Ultrasonic distance sensors are designed to measure distance between the source and target using ultrasonic waves. We use ultrasonic waves because they are relatively accurate across short distances and don't cause disturbances as they are inaudible to human ear. HC-SR04 is a commonly used module for non contact distance measurement for distances from 2cm to 400cm. It uses sonar (like bats and dolphins) to measure distance with high accuracy and stable readings. It consist of an ultrasonic transmitter,...

Interfacing HC-SR04 Ultrasonic Sensor with PIC Microcontroller

HC-SR04 Ultrasonic Distance Sensor is a popular and low cost solution for non-contact distance measurement function. It is able to measure distances from 2cm to 400cm with an accuracy of about 3mm. This module includes ultrasonic transmitter, ultrasonic receiver and its control circuit. HC-SR04 module has 4 pins : VCC - 5V, +ive of the power supply TRIG - Trigger Pin ECHO - Echo Pin GND - -ive of the power supply TRIG and ECHO pins can be used to interface this module with a...
